product worked as expected and arrived in a reasonable time.

After shopping around at my local auto parts stores and not liking what they had in stock I decided to go on line and BANG found Autoplicity.com and they had just exactly the black finished lug nuts that I was looking to give my Trailblazer SS a different look with the stock wheels, 5 ⭐️ 's and definitely will recommend them, thanks again Autoplicity.
